The next day Ned had fever, the day after that he was worse, and on the third day he became unconscious. Then he passed through a time, the length of which he could not guess, but it was a most singular period. It was crowded with all sorts of strange and shifting scenes, some colored brilliantly, and vivid, others vague and fleeting as moonlight through a cloud. It was wonderful, too, that he should live again through things that he had lived already. He was back with Mr. Austin. He saw the kind and generous face quite plainly and recognized his voice. He saw Benito and Juana, Popocatepetl and Ixtaccihuatl; he was on the pyramid and in it, and he saw the silver cone of Orizaba. Then he shifted suddenly back to Texas and the wild border, the Comanche and the buffalo.
His life now appeared to have no order. Time turned backward. Scenes occurred out of their sequence. Often they would appear for a second or third time. It was the most marvelous jumble that ever ran through any kaleidoscope. His brain by and by grew dizzy with the swift interplay of action and color. Then everything floated away and blackness and silence came. Nor could he guess how long this period endured, but when he came out of it he felt an extraordinary weakness and a lassitude that was of both mind and body.
His eyes were only half open and he did not care to open them more. He took no interest in anything. But he became slowly conscious that he had emerged from somewhere out of a vast darkness, and that he had returned to his life in the dungeon under the sea.
His eyes opened fully by automatic process rather than by will, and the heavy dark of the dungeon was grateful then, because they, too, like all the rest of him, were very weak. Yet a little light came in as usual with the fresh air from above, and by and by he lifted one hand and looked at it. It was a strange hand, very white, very thin, with the blue veins standing out from the back.
It was almost the hand of a skeleton. He did not know it. Certainly it did not belong to him. He looked at it wondering, and then he did a strange thing. It was his left hand that he was holding before him. He put his right hand upon it, drew that hand slowly over the fingers, then the palm and along the wrist until he reached his shoulder. It was his hand after all. His languid curiosity satisfied he let the hand drop back by his body. It fell like a stone. After a while he touched his head, and found that his hair was cut closely. It seemed thin, too.
He realized that he had been ill, and very ill indeed he must have been to be so weak. He wondered a little how long it had been since he first lapsed into unconsciousness, and then the wonder ceased. Whether the time had been long or short it did not matter. But he shut his eyes and listened for the last thing that he remembered. He heard it presently, that low roll of the sea. He was quite sure of one thing. He was in the same submarine dungeon of the famous Castle of San Juan de Ulua.
